Improvement in spinning-jacks



UNTTED STATES PATENT OEEICED FREDERICK C. WERNER, OF BEACON FALLS, CONNECTICUT.

IMPROVEMENT lN SPINNING-JACKS.

Specification forming part of Letters Patent No. 415,547, dated December 20, 1864.

To @ZZ whom t may concern.-

Be it known that l', FREDERICK C. WER- NER, ot' Bea-von Falls, in the county of New Haven and State of Connecticut, haveinvented a new and Improved Friction-Regulator for Spinning Jacks; and I do hereby declare that the following is a full, clear, and exact description thereot, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings,forming part of this specification, in whichlfigure l represents a plan or top view of this invention. Eig. 2 is a longitudinal ver tical section ot' the same, the line .r x, Fig. 1, indicating` the plane ot' section.

Similar letters ot' reference indicate corresponding parts.

This invention consists in the combination, with the carriage ot' a spinning-jack, which is provided with a suitable tappet, and with the belt-shipper which throws the drivingbelt of the spinning-jack from the fast to the loose pulley, and vice versa, ot' a movablebar with inclined or chainfered ends in such a manner that whenever a stretch of yarn is made the driving-belt is made to shift entirely on the loose pulley, and the spinner is enabled to Vbreak the speed ot' the spindles and turn them backward much easier and quicker than with an ordinary spinning-jack; but just as soon as he begins to wind up, the tappet projecting from the carriage will touch the movable bar, thereby causing the belt to move from the loose onto the fast pulley just t'ar enough to do the winding, and keeping it in this position until the tappetpasses the movable bar, when the belt passes again to the loose pulley, allowing the machine to be stopped, it' wanted.

ln an ordinary spinning-jack the spinnerpushes the carriage in gear and simultaneously therewith the belt is thrown from the loose on the fast pulley, and the roving and the spindles are set in motion. The spinner, in drawing the cai riage to the outer end of its stretch, makes yarn from the roving, and as soon as suflicienttwist is in the yarn the belt is pushed back on the loose pulley, but is not allowed to clear the fast pulley entirely. It is partly lelt on to help the spinner turn the spindles while winding the stretch ot' yarn onto the bobbins or cops; but before he can begin to wind up he must stop the spindles, which he does by layinghis hand on the crankwheel and holding back on it till it stops; then he turns the c ank-wheel about half-way backward, in order to bring the threads from the top of the spindles to the part where he desires to wind the yarn. rlhe breaking ot' the speed of the spindles and the backwald turning he has to do against a portion of the driving-belt acting in the opposite direction, and thereby the operation of spinning is rendered tiresome and laborious. `These disadvanta ges are obviated by lny invention, which will be readily understood from the following t description.

A represents the carriage, which is constructed in the ordinary manner, and'which is supported by wheels B, and moves back- Ward and iorward on the track C. D is the drivin g-shaft, which carries the fast and loose pulleys E E', Iand from which motion is iniparted to the spindles by a belt, F, extending over a pulley, Cr, on said driving-shaft, and thence over suitable pulleys and tighteningrollers tothe drum H in the carriage.

The position of the belt I, which imparts motion to the shaft D, is governed by a beltshipper, J which is subjected to the action of the spring a, so that when left to follow that action, said belt-shipper throws the belt on the loose pulley E. Whenever this takes place, the motion of the shaft D and that ot' the spindles stops.

l In order to obtain the assistance of the belt I in winding up, the belt-shipper J connects by a forked aun, b, with a rock-shaft, c, which extends parallel to the track7 and has its bearings in lugs d, between said track, or in any other convenient locality in close proximity to it. From this rock-shaft rise two or more arms, c, which support a long flat bar, f, the ends of which are chamfered off, as clearly shown in Fig. 1 ofthe drawings. This bar extends under the carriage, while the latter is in motion, and a tappet, g, attached to or projecting from some convenient part of said carriage, is so arranged in relation to the bar j" that when the carriage is at either end of its stretch said tappet is not in contact with the bar, and the belt-shipper is free to follow the action ot' the spring a, and to throw the belt I on the loose pulley E; but when the carriage moves along` on its track the tappet strikes the edge of the bar and turnsit back to the position shown. in Fig. l. The belt-shipper is thereby moved in the direction of the arrow marked on it in said gure, and the belt I is thrown partially on, the fast pulley E. In this position the belt assists the spinner in giving motion to the spindles for the purpose of Winding up, and after the tappet on the carri'age has passed the barf the belt-shipper is free to follow the spring a and to throw the belt on the loose pulley E, so as to stop the machine, if it is desired. The labor ofthe spinneris thereby considerably reduced. When the carriage arrives at the outer end of its stretch, the belt I passes automatically on the loose pulley E, and the motion ofthe spindles stops, and so soon as the carriage begins to move toward the inner end ofits stretch for the purpose of Winding up, the belt I passes partially on the fast pulley, and the spin ner obtains the assistance of the same in Winding; up.

This device is very simple in its construction and easily understood. It can be readily attached to spinning-jacks of any desired construction, andwhen once properly adjusted it is not liable to get out of order.

In order to make the tappet adjustable for more or less friction, it maybe made with slots for the reception of' its attaching-screws.

I claim as new anddesire to secure by Letters Patent- The movable bar f, applied in combination with the belt-shipper J, carriage A, and tappet g, inthe manner and for the purpose substantially as set forth.

FREDERICK C. VERNER.
